Since hardly any Getbiggers meet your criteria, they don't have to worry about potential violence.

As for me... I find my extra size keeps me out of a lot of trouble, but I never wear any douche bodybuilding clothing, so I don't really call any attention to myself.
An example off it helping off the top of my head.... I gave driving a Taxi cab a shot for about a year, and many of the other drivers in our company had problems with being held up by gunpoint, problems with passengers, etc, but I avoided it. There were a few times, that it looked like it was going to get a bit sketchy, but I think my size served as a deterrent. This has also been true for various Security, bouncing jobs, etc, that I have had over the years.
